With massive paws and giant claws, the mighty grizzly can tread just about anywhere it wants, even up a tree. And now, you can bolt this ground-grabbing traction to your rear end with the Yukon Gear & Axle Grizzly Locker. The ultimate mechanical positive-locking differential, the Yukon Grizzly locker provides 100% power to both tires while allowing disengagement for turns.
Designed to dominate off-road, street, drag and circle track racing, the Yukon Grizzly differential is built as tough as its namesake. The case is forged from 8620 chromoly, and the internal are 8620 triple-alloy. Inner clutch teeth are cut with a larger base radius—way stronger than back-cut designs. Plus, the larger teeth avoid breakage against shock-loading and during freak axle breaks.
Proudly assembled right here in the USA, all the internal parts are hand fitted for the highest quality. And best yet, Yukon Gear & Axle puts their money where their mechanical locking diff is—they back your Grizzly Locker with a 1-year warranty should failure occur.

If you can't afford or don't want a selectable locker then this is the one you want. If you are rock crawling or doing some serious 4 wheeling then you have want this locker. Built like a brick house, the Grizzly is more advanced then the Detroit locker and the price is comparable. I chose the Grizzly over the Aussie locker for the rear diff since this one is used all the time and wanted something heavy and reliable. Lastly, call these guys for a better deal then they have posted. Great company.
